FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 673,204, dated April30, 1901.

Application filed July 25,1898. Serial No. 686,786. KNo model.)

To all whom it may concern:

Be it known that I, THOMAS F. HANDLY, a citizen of the United States ofAmerica, residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inFire-Extinguishers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to certain new and useful improvements infire-extinguishers.

The objectof my invention is to construct a fire-extinguisher having anacid-receptacle suspended therein, which is adapted to be inverted bymeans of the outlet-tube and suspended therefrom in such a manner that acomplete neutralization of the acid contained therein will be efiected.

My invention consists in providing a suitable cage to contain theacid-receptacle which is pivotally secured to a suspending-rod securedto the outlet-tube and 'a sealing means for the mouth of theacid-receptacle.

My invention further consists in the novel combination and arrangementof parts hereinafter more fully described, illustrated in theaccompanying drawings, and particularly pointed out in the claims.

In describing the invention in detail reference is had to theaccompanying drawings, in which- Figure 1 is a central vertical sectionof a fireextinguisher embodying my invention, showing theacid-receptacle in its sealed position in full lines and in dotted linesits position when the outlet-tube is turned to break the seal and permitthe inversion of the acidreceptacle and its cage. Fig. 2 is a detailperspective view of the cage which holds the acid-receptacle. Fig. 3 isa horizontal sectional view of the extinguisher, showing the normalposition of the cage in full lines and in dotted lines the positions itassumes when the seal of the acid receptacle is broken. Fig. 4 is anunderneath plan view of the sealing-cap. Fig. 5 is a vertical sectionalview of the upper portion of the outlet-tube, the coupling therefor, anda part of the closurecap for the extinguisher-receptacle. Fig. 6

is a side view of a part of the acid-receptacle and its cage, showing amodified form of sealing-cap.

the ring 22 of the cage.

Referring to the drawings, in which like numerals of reference indicatecorresponding parts throughout the several views, 1 indicates thefire-extinguisher receptacle, having a mouth or opening 2, and abottoln3, suitably secured thereto.

4 denotes the alkaline solution contained in the extinguisher shown inbroken lines.

collar 7, which prevents the tube being pulled outwardly when operated.The outlet-tube extends above the closure-cap 5 a certain distance, asshown in Fig. 4:. v The extending end of the outlet-tube is adapted toreceive a coupling 11, which is interiorly screw-threaded, as at 12.Formed integral to one side of the coupling is a discharge-pipe 13,which is adapted to receive or have suitably secured thereto a hose-pipe14 for carrying off the extinguishing solution. The upper end of thecoupling is interiorly screw-threaded, as at 15, and is adapted toreceive the supporting end 16, which is exteriorly screw-threaded, ofthe operating-handle 17. The supporting end of the handle is also usedas a closure or stopper for the upper end of the coupling 11. Secured tothe outlet-tube, on the upper part thereof, is a clamp 18, which haspivotally secured thereto a suspending-rod 19, which is of the length ofthe cage containing the acidreceptacle. The rod is bent at right angles,as at 20, and is pivotally secured, as at 21, to This rod supporting thecage containing the acid-receptacle when the cage has been inverted bythe turning of the handle 17, and owing to the rod being pivotallysecured to the ring 22, allows for a to-and-fro motion of the cage andacid-receptacle.

The cage for holding or sustaining the acidreceptacle is formed of aseries of rods 23,

bent to conform to the shape of the acid-' receptacle 24, and the upperends of these rods are secured to a ring 25, which is of less diameterthan the ring 22. The upper ends of the rods 23 are secured to the ring25 as at 25 and the lower ends as at 22.

26 indicates a sealing-cap for the mouth of the acid-receptacle. I mayalso term this a sealing or securing plate. The cap or plate 26hasformed integral with its lower face a series of lugs or projections 29for securing the mouth of the receptacle in the desired position. Thecap or plate 26 also acts as a means for securing the cage and thereceptacle in an elevated position until the same are inverted by meansof the outlettube. The upper face of the cap or plate 26 is pivotallysecured to a rod 28, as at 28, and this rod is pivotally secured to thelower face of the closure-cap 5, as at 29.

In Fig. 5 I have shown a modified form of a rod for suspending thesealing cap or plate, and it consists of a rod 30, which is pivotallysecured to the upper face of the cap or plate, as at 31, and theopposite end of the rod is rigidly secured to a spring 31. This spring31 is turned upward at 32 to prevent the displacement thereof from theguides 33, in which the spring is slidably secured. The guides areformed integral with the lower face of the closure-cap 5.

It will be readily apparent that when the outlet-tube is turned by meansof the handle 17 the neck of the acid-receptacle will be dislodged fromthe sealing means, and owing to the cage which contains theacid-receptacle being pivotally secured to the suspendingrod it willimmediately invert itself and assume the position shown in verticaldotted lines in Fig. 1.

The acid-receptacle will discharge the acid contained therein on itsdownward movement, and when finally suspended in the position as shownin Fig. 1 the entire amount of acid will be eliminated thereby,resulting in a complete neutralization of the acid, and the necessaryquota of extinguishing and expelling gas will have been generated. Thesolution will then be thoroughly impregnated with the gas.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of my invention.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is
